According to Ars Technica
, the User Account Control
in Vista (that is annoying to users because it puts up so many dialog boxes to confirm any system change) is able to be disabled. But is it really a good thing that you can turn it off? That means that another application (given the ok from the dialog boxes) could turn it off for you. And since the dialog boxes aren't very descriptive as to why the process needs elevated privileges, the new screen saver you think you downloaded could be a virus that disables your user account control notification as step one, and proceeds to muck up your system without your knowledge or OK and allow other nasties to muck up your system.
Since security is one of the big pillars they are touting in Vista, it's sad to see all the good security disabled so easily. No matter how annoying it is, it's better than malicious code infecting your system.
